--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
There is redirect_to_unreachable and a couple of other places (though at least
half of them are related to devirtualization which shouldn't be happening
here):
grep builtin_decl_unreachable ipa*
ipa.cc: target = cgraph_node::get_create (builtin_decl_unreachable ());
ipa-fnsummary.cc: = cgraph_node::get_create (builtin_decl_unreachable ());
ipa-prop.cc: target = builtin_decl_unreachable ();
ipa-prop.cc: tree new_target = builtin_decl_unreachable ();
So, I'd add a breakpoint on builtin_decl_unreachable and see where it is called
for this code.
